Abstract: This invention relates to remediation and decontamination of sediments and soils contaminated with organic and inorganic contaminants. Environmentally stable products are produced when certain additives such as calcium oxides are mixed with the contaminated materials. In the process, the mixture is heated to produce a molten reaction product with at least part of an excess amount of oxygen mixture or air continuously bubbled through the melt (16) in order to provide mixing and achieve high thermal destruction and removal efficiencies of the organic contaminants. The melt (16) is then quickly quenched in moist air, steam or water to avoid the transformation of the amorphous material into crystals. The inorganic contaminants such as chromium, nickel and zinc are incorporated and completely immobilized within the amorphous silicate network. The amorphous material can be pulverized to yield a powder which evinces cementitious properties by blending it with other materials to produce blended cements.

Abstract: A spherical hydraulic substance comprising a hydraulic powder based on CaO, SiO2, Al2O3 and Fe2O3, wherein at least the surface of the powder is melted for smoothening and then cooled and the powder has a particle diameter of 500 νm or less and a means circularity of 0.7 or above. This substance is produced either by melting the starting material mainly comprising the above oxides, followed by splashing to effect cooling for solidification, or melting at least the surface of the hydraulic substance, followed by cooling for solidification. Alternatively it is produced by mixing a hot substance such as iron making slag in a state molten or heated above 500 °C with a dried, calcined, sintered or molten starting material based on at least one oxide selected among CaO, SiO2, Al2O3 and Fe2O3 and splashing the molten mixture to effect cooling for solidification. Since this substance is a minute spherical particle having a smooth surface and a shape close to a true sphere, it is remarkably excellent in fluidity and strength when kneaded with water.

Abstract: An apparatus for producing a spherical hydraulic material comprises a melting furnace (1) for melting raw materials of a hydraulic material and/or the hydraulic material, fine granulation means for finely granulating the molten material (2) such as a nozzle (4) or a high speed rotary member, a chamber (5) for accepting the finely granulated material, cooling it and converting it into spherical fine powder, and means (6, 7) for recovering the spherical fine powder. When the material molten in the melting furnace enters the chamber and is finely granulated, the molten material is immediately formed into a complete sphere because its surface tension is relatively great, and is cooled and recovered as the spherical fine powder. The resulting spherical hydraulic material is highly fluidized by a small amount of water, and turns to a molded article having high strength and high durability, and moreover, having an excellent dimensional accuracy. Spherical hydraulic material which is approximately in the form of a complete sphere, is extremely smooth on the particle surface and exhibits high fluidity can be obtained by using this apparatus. This hydraulic material can be produced without limiting the blend ratio of the starting components, and various ashes of an incinerator can be utilized as the hydraulic material. Moreover, maintenance becomes easy.

Abstract: A synthetic slag is produced by a high temperature combustion reaction between coal ash having a high carbon content, and a source of lime such as cement kiln dust. The carbon content of the coal ash is oxidized by oxygen gas, which typically is derived from air or an air/oxygen combination in an exothermic reaction and the heat generated is exploited in the melting process. In this way the gaseous products will typically comprise nitrogen, unreacted oxygen and carbon dioxide, and heat energy can be readily recovered from the hot off gas products evolving during the combustion reaction. The synthetic slag may be pelletized and employed as lightweight mineral aggregate or milled to cement fineness to provide slag cement.

Abstract: The invention relates to a method for manufacturing cement clinker whereby the raw meal is initially subjected to preparatory processing, e.g. by comminution, homogenization and/or drying, and, eventually, nodulized and burned, with the nodulization process itself taking place in a stationary burning reactor. By the method according to the invention a sulphatic compound is added to the raw meal in a sufficient quantity before introducing the raw meal into the stationary burning reactor or directly into the stationary reactor, e.g. through the combustion air or together with the fuel. It is an essential requirement that the sulphate content of the calcined raw meal is considerably higher than the alkali oxide content.

Abstract: The specification discloses a process for heating solid particulate materials. The process comprises entraining the solid particulate materials in a gas to form a stream of gas containing entrained particles and contacting this stream with a stream of hot gases. The contact between the two streams is performed in such a manner that at least a portion of the solid particulate material is heated rapidly and the heated and unheated particles enter flow patterns in which contact between the particles and with interior surfaces of a contact chamber is minimized. A heating and treatment chamber for applying the process to the treatment of solid particulate materials is disclosed. The specification also discloses a molten bath reactor combined with the chamber for heating and treating solid particulate materials. Hot off gases from the molten bath reactor can be passed through the chamber and treated particulate material from the chamber can be inserted in the molten bath reactor or partially recycled through the chamber.
